From a vacuum chamber to a burger, we take a look at the 10 biggest things in the world.
A hamburger is a sandwich consisting of one or more cooked patties of ground meat, usually beef, placed inside a sliced bun. Hamburgers may be cooked in a variety of ways, including pan-frying, barbecuing, and flame-broiling. Hamburgers are often served with lettuce, bacon, tomato, onion, pickles, cheese and condiments such as mustard, mayonnaise, ketchup, relish, and chiles.
The term urger can also be applied to the meat patty on its own, especially in the UK where the term patty is rarely used. The term may be prefixed with the type of meat or meat substitute used, as in urkey burger, ison burger, or veggie burger.
Hamburgers are sold at fast-food restaurants, diners, and specialty and high-end restaurants . There are many international and regional variations of the hamburger. (source : wikipedia)
